Troubleshooting
Steady Flow (PTR) – More than
20L per day
This may be caused by excessive water
supply pressure, a faulty PTR Valve or a
faulty thermostat. Turn off the electricity
supply and contact Dux
on 1300 365
115.
High Electricity Bills
• Is the Pressure & Temperature
Relief Valve discharging too much
water?
• Is one outlet (such as the shower)
using more hot water than you
think? See “No Hot Water”.
• Is there a leaking hot water pipe or
dripping hot water tap? A small leak
can waste a large quantity of hot
water.
• Replace faulty tap washers and have
your plumber rectify any leaking
pipework.
